CHARLES C. TROXELL, OF CORNWLLON-TH-HUDSON, NEW YORK, AS-

SIGNOR OF ONE-HALF TO JOSEPHIE M. COZZENS,VOF NEWBURGH,

YORK- STONE AND DIRT LOADING MACHINE.

SPECIFCATION forming part of Letters Patent No. 677,823, dated July 2, 1901.

Appia-trimmed october 6,1900; serial No. 32,215. (No moda.)

A further purpose of the invention is to` construct a machine of thecharacter described whichiwill eectually and automatically pick up, maintain, and finally deliver stones'or dirt to any desired receptacle;

The invention consists in the novel construction and combination of the several parts,as will be hereinafter fully set forth,`

and pointed out in the claims.

Referenceis to behad to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of the improved machine, the guards which serve to prevent the material from sliding 'off the carrier being shown in working position. Fig. 2 is a View similar to Fig. 1, the guards being shown elevated andthe machine being in position to be drawn to or from a eld. Fig. 3 is a plan view of the machine, and Fig. 4 is a transverse section taken practically on'the lines 4 4 of Figs. 1 and 2. The frame of the machine consists of two parallel side beams 10, which are preferably constructed of T-iron. An axle 12 is suitably journaled at the rear portion of vthe frame, and supporting-wheels 13 are secured to said axle. Boxes 14 are located at the upper portion of the forward end of the frame,

and these boxes serve as bearings for a shaft 15. The boxes are adjustable on the frame, being usually provided with teeth which mate with teeth 16, formed on the frame, as is shown in the drawings. The boxes 14 are made thus adjustable in order to keep endless chains 19 under proper tension. These ipchains pass overllanged pulleys 17, secured ,on the shaft 15,' as shown in Fig. 3, and over larger sprocket-wheels 18, attached to the axle 12, as shown in Figs. l and 2. These tervals by kcross-bars 20, and lingers 21 are carried by these cross-bars, the upper ends of the fingers being curved in such manner that the curved portions of the fingers on the upper stretchesiof thechains or belts face the forward portion ofthe machine. In frontof tl 1e crossbars 2O slats-22 are attached Ato thesaid belts, the slats being pro-J vided with end sections 23, which are'preferablyv at right angles to the body portions of the slats. The slats and their uprights, to-

gether with the cross-bars and their fingers,

serve as pockets for the reception of stones which are picked up by the machine and are to be delivered by it to a suitable receptacle.

The central portion of, the frame is .supported by easter-wheels 24, and these caster- Wheels are located at the ends of a cross-bar 25, which is below the main frame, and horizontal side bars 26 are attached pivotally to the side beams of themain frame, near their lower ends, and the cross-bar 25 is attached to these horizontal bars 26, near the forward ends of the bars, by suitable arms 27, as illustrated inFigs. l and 2.

Standards 28 arecarried up from the end portions of the cross-bar 25. These standards are connected with the horizontal bars 26,'and at or nearthe upper ends of the stand- -endless chains are connected at suitable inl ards a series of apertures 30 is produced.V

These standards are connected with the side beams of the main-frame by pins 29, passed through ythe said side beams and any one of loe downward and curve forward at theirlower ends, as shown in Figs. 1 and 2 Near each end of the said cross-bar 34 a bar 36 is attached, and these bars are carried downward between the supporting-wheels 13 and are attached to the rear portion of crescent-shaped or semicircular guard-plates 37, the forward, ends of which guard-plates are connected with chains 38, attached also to the horizontal bars 26 of the main frame. These chains 38 are slack, as shown in Fig. l, when the guards are in engagement with the ground,

which is their position when the machine is to be worked, and these guards serve to prevent the stones picked up by the fingers 21 from sliding out at the end portions of the pockets on the endless chains as the pickedup stones are being deliveredat 'the front end l of the machine.

In the operation of the machine the fingers 21 as they approach the ground pick up stones v or any loose material in their path and carry said-material upward, dumping the material at the upper end of the machine into a cart or wagon body A, connected with the cross` bar 25 by a draft-rod B or its equivalent. When dirt is to be picked up instead of stones or like substances, the ends of the pocketson the endless chains are closed by suitable covers-as, Vfor example, boards-and one or more of such covers are secured to the rear 1 fingers 35 to prevent the escape of the material lfrom the pockets.

It is 'very desirable tolift the guards 37 from]v the ground when the machine is in transit to and from the field of operations. To that end I employ a lever 39, preferably located at the right-hand side of the machine, which lever likewise engage with the ground; but whenv the lever 39 is pressed downward, as shown in. Fig. '2, the guards 37 and'fingers 35 are raised rearward, so that they clear the ground.

The lever 39 passes through the loop-section l 44, formed upon a curved bar 43, which bar is secured to the right-hand upright 31, as shown especially in Figs. 1 and 2, and receives the right-hand horizontal bar 26 of the frame.

The loop portion of the curved bar 43, which is l a guide-bar, is provided with apertures 45,and

a pin 46 is passed through these apertures and the slot 40 in the lever 39, serving to hold the lever 39 in its adjusted position.

Having thus described my invention, IV

claim as new and desire to secure by Letters Patent- 1. In combination,a wheel-supportedframe, endless carriers mounted to travel on the frame, pockets formed on the 'carriers,'fingers forming parts of said pockets, which fingers are adapted to pick up material, guard-fingers at the rear of theframe, guard-plates coacting with the fingersfbetween which guardplates the carriers pass, and an adjusting mechanism for the fingers and guard-plates, as described.
